Subject. The study analyzes generally accepted approaches to assessing the value of companies on the basis of financial statement data of ExxonMobil, Chevron, ConocoPhillips, Occidental Petroleum, Devon Energy, Anadarko Petroleum, EOG Resources, Apache, Marathon Oil, Imperial Oil, Suncor Energy, Husky Energy, Canadian Natural Resources, Royal Dutch Shell, Gazprom, Rosneft, LUKOIL, and others, for 1999—2018. Objectives. The aim is to determine the specifics of using the methods of cost, DFC, and comparative approaches to assessing the value of share capital of oil and gas companies. Methods. The study employs methods of statistical analysis and generalization of materials of scientific articles and official annual reports on the results of financial and economic activities of the largest public oil and gas corporations. Results. Based on the results of a comprehensive analysis, I identified advantages and disadvantages of standard approaches to assessing the value of oil and gas producers. Conclusions. The paper describes pros and cons of the said approaches. For instance, the cost approach is acceptable for assessing the minimum cost of small companies in the industry. The DFC-based approach complicates the reliability of medium-term forecasts for oil prices due to fluctuations in oil prices inherent in the industry, on which the net profit and free cash flow of companies depend to a large extent. The comparative approach enables to quickly determine the range of possible value of the corporation based on transactions data and current market situation.

Submerged Arc

The Arctic region is expected to play an extremely prominent role in the future of the oil and gas industry as growing demand for natural resources leads to greater exploitation of a region that holds about 25% of the world’s oil and gas reserves. It has become clear that ensuring the necessary reliability of Arctic industrial structures is highly dependent on the welding processes used and the materials employed. The main challenge for welding in Arctic conditions is prevention of the formation of brittle fractures in the weld and base material. One mitigating solution to obtain sufficiently low-transition temperatures of the weld is use of a suitable welding process with properly selected parameters. This work provides a comprehensive review with experimental study of modified submerged arc welding processes used for Arctic applications, such as narrow gap welding, multi-wire welding, and welding with metal powder additions. Case studies covered in this article describe welding of Arctic steels such as X70 12.7-mm plate by multi-wire welding technique. Advanced submerged arc welding processes are compared in terms of deposition rate and welding process operational parameters, and the advantages and disadvantages of each process with respect to low-temperature environment applications are listed. This article contributes to the field by presenting a comprehensive state-of-the-art review and case studies of the most common submerged arc welding high deposition modifications. Each modification is reviewed in detail, facilitating understanding and assisting in correct selection of appropriate welding processes and process parameters.

The article deals with privatization in Russia’s energy sector with a special focus on a recent purchase of the private TNK-BP by the state-owned Rosneft. The author analyses the past, present and future privatization deals related to the Russian oil, gas and power generation industry as compared to accumulated international experience. For instance, the article displays the ways the Norwegian, Brazilian, French and British authorities privatized national strategic energy assets. The study presented in the article also aims to find out key advantages and disadvantages of state or private ownership in the Russian and global energy industry. For example, it sheds light on some considerable achievements of the Russian state-controlled companies in oil production amid a widespread belief that more than a decade-long growth in the Russian oil industry is due only to private firms that were created in the 1990s. Additionally, the state-controlled Norwegian oil and gas firm Statoil that shows strong operational and financial results on the Norwegian Continental Shelf and abroad is also in the spotlight of the current study. In line with the mentioned takeover of TNK-BP the author examines outcomes of the reorganization of RAO UES of Russia (the dismantled Russian electric power monopoly) that was seen as a massive privatization of the national power industry. Moreover, the study presents two groups of interests prevailing in the Russian government and energy business to give an outlook on the Russian energy industry.

Corrosion Under Insulation

Corrosion under insulation (CUI) is a serious issue in the oil and gas industry, with failures often occurring without warning and having devastating effect. When expensive redesign is not possible or practical, operators have a number of options open to them to mitigate the risk of CUI; these include the use of various protective coatings or thermally sprayed metals. Despite a number of technologies presently available, the industry is yet to establish an accepted laboratory test method for the performance benchmarking of products. This has, in the past, damaged confidence in some solutions and hampered the selection and further development of CUI coatings. As a result, the subject of accelerated laboratory testing for CUI coatings is now receiving significant attention across the industry with joint industry programs proposed in both Europe and North America. This paper will examine state-of-the-art accelerated CUI testing, evaluating the advantages and disadvantages of the existing methods available. It will then offer a detailed description of a test method that has been in use since 2004, testing more than 300 specimens and assessing a wide range of coating technologies. The reproducibility of the test program will be established by the presentation of a range of data including results obtained from a third-party test house. The third-party results will then be correlated with a seven-year case study from an end user perspective provided by Santos, a major Australian oil and gas exploration and production company, from experiences at their Port Bonython facility in SA.

In Kuwait, industrial boilers are used extensively in food, chemical, oil and gas, textile, pharmaceutical, power plant sectors for generation steam. As a crucial item in industries, its maintenance is of utmost importance. As there are two main maintenance approaches such as reactive maintenance and preventive maintenance, the application of a typical maintenance is definitely based on types of application, safety concern, and cost benefit ratio. If a boiler is down for few days, it may cause huge loss as it interrupts subsequent steps especially in process industries. In this research, the importance of preventive maintenance strategy for steam boilers in Kuwaiti industries has been studied. Based on relative advantages and disadvantages, a proper strategy is proposed for better management and effective maintenance of boilers.

The problems of the current ecological situation in the oil-producing regions are being investigated. The analysis of the impact of the growth of hydrocarbon production on the environment has been carried out. The main causes and sources of pollution have been identified, starting with the process of developing oil and gas fields and including directly extracting and processing oil and gas resources. It is noted that the main reason for the growing environmental hazard is the deterioration and depreciation of equipment and the low share of innovative activity of oil companies. The main methods of utilization of oil production wastes, which are currently used in world practice, have been analyzed. Some technologies for processing oil sludge with obtaining a secondary product are considered. Their main advantages and disadvantages associated with the features of the technological process are described. The possibility of obtaining inert soil, building material, expanded clay and other materials using drill cuttings has been evaluated. The complex separate processing of drilling waste has been determined as the most effective and promising. Its main advantages associated with the complete utilization of all components of oil sludge, as well as the problems of introducing this technology, are given.

Line Segmentation

As part of a major pipeline expansion, two deactivated 24″ diameter pipeline segments with a combined length of 192 kilometres will be assessed and upgraded to operational status. These line segments include a 42 kilometre section within the North Thompson valley of British Columbia, and a 150 kilometre segment through the Rocky Mountains of Alberta and British Columbia. Reactivating the lines to operational condition is a multi-staged process, which will be partially guided by a National Energy Board Condition requiring the issuance of a certificate from an independent certifying body that the system is fit for service and meets all applicable requirements of CSA Z662, Oil and Gas Pipeline Systems. This certificate must be unconditional and remain in effect for a period of 5 years. The need for unconditional certification of fitness for service drives the need for a comprehensive assessment of the pipeline condition using a broad slate of inline inspection technologies. Tools were selected for the assessment of deformations, metal loss, manufacturing anomalies and cracking. The lines were maintained with a low pressure nitrogen blanket for between 9 and 13 years prior to the start of the reactivation work and it was therefore not possible to run the tools using service fluid. Several options were considered for propelling the inline inspection tools including nitrogen, compressed air and water slugs in compressed nitrogen or air. Each method has advantages and disadvantages and modelling was carried out to simulate the transport of the tools through each segment. The modelling needed to account for pipe elevation changes, wall thickness changes, valves, tool drive friction, acceptable tool velocity, and the pressure of the drive medium in the pipeline. The modelling focused on the following constraints: i. Ensure ILI data quality ii. Ensure safety considering the potential presence of defects in the lines iii. Minimize risk iv. Minimize overall cost These constraints guided a flow modelling/feasibility study for inspecting the lines with the 4 tools. The objective of the study was to determine the optimum configuration of propellant, inspection tools, and line segmentation while ensuring a safe, economical operation resulting in optimal data collection. The paper will provide some background on the line segments being reactivated and pressure limitations that were adopted for ILI runs. The majority of the content will focus on the determination of tool drive technique, how simulation occurred and how the actual execution of the runs compared. Details regarding the challenges and troubleshooting required to successfully complete the integrity surveys will also be discussed in depth.
